in the figure: 1. a housing; 2. a rear splint; 3. a front splint; 4. an upper level space; 5. a lower layer space; 6. a cold medium inlet; 7. a cold medium outlet; 8. a first heat exchange medium inlet; 9. a first heat exchange medium outlet; 10. a second heat exchange medium inlet; 11. a second heat exchange medium outlet; 12. a lower baffle plate; 13. an upper baffle plate; 14. a heat exchange tube.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

A shell and tube heat exchanger as shown in fig. 1, which comprises a shell 1, wherein a front clamping plate 3 is arranged at the front end of the shell 1, a rear clamping plate 2 is arranged at the rear end of the shell 1, a cold medium inlet 6 is arranged on the front clamping plate 3, a cold medium outlet 7 is arranged on the rear clamping plate 2, a first heat exchange medium inlet 8 and a first heat exchange medium outlet 9 are arranged at the upper side of the shell 1, a second heat exchange medium inlet 10 and a second heat exchange medium outlet 11 are arranged at the lower side of the shell 1, an upper space 4, a middle space and a lower space 5 are arranged in the shell 1, a plurality of heat exchange tubes 14 are arranged in the upper space 4 and the lower space 5, the heat exchange tubes 14 are arranged in a corrugated structure, the first heat exchange medium inlet 8 and the first heat exchange medium outlet 9 are communicated with the upper space 4, and the second heat exchange medium outlet 11 and the second heat exchange medium inlet 10 are communicated with the lower space 5, the cold medium inlet 6 and the cold medium outlet 7 are communicated with the middle layer space, an upper baffle plate 13 is arranged on the upper side wall surface in the middle layer space, a lower baffle plate 12 is arranged on the lower side wall surface in the middle layer space, the upper baffle plate 13 and the lower baffle plate 12 are arranged in a staggered mode, and a plurality of through holes are formed in the upper baffle plate 13 and the lower baffle plate 12.

In the using process, a heat medium is conveyed to the upper layer space 4 and the lower layer space 5 of the shell 1 through the first heat exchange medium inlet 8 and the second heat exchange medium inlet 10, the heat medium flows in the heat exchange tubes 14 in the upper layer space 4 and the lower layer space 5, meanwhile, a cold medium enters the middle layer space of the shell 1 through the cold medium inlet, when the heat medium flows through the heat exchange tubes 14 in the upper layer space 4 and the lower layer space 5 and the cold medium flows in the middle layer space, the heat transfer between the cold medium and the heat medium is realized, the heat exchange is realized, finally, the heat medium flows out through the first heat exchange medium outlet 9 and the second heat exchange medium outlet 11, and the cold medium flows out through the cold medium outlet 7.

The heat exchange tube 14 is provided with a corrugated structure, so that a heat medium can fully circulate in the heat exchange tube 14, and the heat exchange between the heat medium and a cold medium can be facilitated.

The upper baffle plate 13 and the lower baffle plate 12 are arranged to facilitate the circulation of the cold medium in the middle space in an S-shaped trend, thereby facilitating the sufficient heat exchange between the hot medium and the cold medium.

The upper baffle plate 13 and the lower baffle plate 12 are respectively provided with a plurality of through holes, so that the impact of a cold medium on the upper baffle plate 13 and the lower baffle plate 12 can be reduced.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
